For Spas using only
ONE
"J"
Series Pump/Motor
and the pump is black.
This
is a
2
speed
motor
operating
on
115v.
All
JWB
spas
with
only
one
pump/motor
uses
this
pump/motor.
The
motor
has
two
windings
so
on
low
operates
heater/filter
and
on
High
gives
you
jet
action.

If you upgraded a 115v control
system to 230v, it does NOT affect the motor.
The motor remains 115v. What it DOES change is
makes the heater more efficient (about 3x more)
and the heater will stay on when the spa is on
High jet. So for small spas built 1993-2001 with
1 pump, your pump is 115v. You can check on the
motor's label to confirm but unless the actual
control system has been modified in the field,
its a 115v, 2 speed pump motor.
